Buy a mirrored perfume tray, or more if you have several projects in mind. Carefully examine them for cracks and scratches before you purchase them.
Buy a package of small or medium adhesive wall mount strips. Flip one perfume tray over, and place four wall mount strips on each corner. Place the tray on the wall as an ornate mirror. Repeat with other trays if you want to make a set of mirrors.
Disinfect the tray with some anti-bacterial soap or solution. Place pastries, fruit, crackers, cheese, hummus, or any other snack food on the tray, and serve it to guests.
Pour champagne or wine into glasses, drape a linen napkin over the tray, and place the drinks on it as a serving tray for guests.
Keep tray on a hall table. Put small trinkets, keys, or mail on the tray after coming inside.
